TEMPORARY BINDER.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed October 24, 1911. Serial No. 656,468.-

lTo all lwhom, t may concern Be it known that I, GE RGE P. W'IceiN- TON, a citizen of the Unite States, residing at the city of Kalamazoo, county of Kalamazoo, and State of Michigan, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to improvements in temporary binders.

My present invention is an adaptation and insome respects'fan improvement upon the apparatus shown in Letters Patent No. 1,010,556, issued to me on the 5th day of December, 1911.

The main objects of this invention are,

first, to provide in a temporary binderl or.

loose sheet holder, an improved adjusting mechanism. Second, to provide an impr'oved temporary binder or loose sheet holder which is capable of very rapid manipulation to permit the insertion or removal of sheets or leaves, and one in which the sheets may be very securely'clamped, the mechanism at the samev time being simple and compact, so thatit may be embodied in small binders. Third, to provide an improved temporary binder or loose sheet holder having a back ,strip or piece which is automatically adjusted upon the adjusting of the binder..

Further objects, and objects relating to structural details, will definitely appear from the detailed description'to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

vThe invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a perspective view of a structure embodying the features of my invention, the cover Jcontaining the adjusting mechanism being shown t open, sheets -or Fig. II

is a detail inside plan view of the structure shown in Fig. I, with the covers eX- tended, the leaves being shown in anupright position. Fig. III is a detail longitudinal section takenon a line corresponding to line 3 3 of Fig. II, with the covers closed. Fig. IV is a detail section taken on lever 31 being shown in its actuated position by full'lines, and in its initial position by `dotted. lines, the pawl 24 being shown in its engaged position by full lines and in its disengaged position by dotted lines. Fig. VII is an inverted detail of the adjusting member 23, with the adjustingleverSl shown in its disengaged position by full lines, and in its engaged position by dotted lines. Fig. VIII is a sectional view taken on a line corresponding to the broken line 8-8 of Fig. VI.` F-ig. IX is a perspective view of one of the clamping bars 13. u

In the drawing, similar reference charac ters refer to similar parts throughout lthe several views, and the sectional viewsare taken looking in ,the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the covers 1 and 2 in the embodiment of my invention illustrated, comprise the body boards 3 and 4 respectively, with outer Walls or cover plates 5 and a suitable finishing binding or covering 6 of cloth, leather, or the like. The body boards are recessed to provide cover chambers 7 and 8 for the covers 1 and 2 respectively. The cover 1 is provided with an inner Wall 9.

At the inner ends of the covers l and 2 are cover bars 10 and 11 respectively, formed of sheet metal folded longitudinally uponthe ends of the cover boards. The folded edges of the cover bars are curved to provide knuckles l12 for' the sheet clamping bars 13. These leaf or sheet clamping bars 13 are formed of fiat strips of metal and are disposed in bearing engagement with the knuckles of the coverbars. The clamping bars 13 are provided with ear-like pintle members 14 which are struck longitudinally from the bars and perforated to receive the l pintles 15, the cover bars `being provided with slot-like openings 16 for these pintle ears. These -knuckle openings are deep enough to permit t-he leaf clamping bars to swing against either side of the cover, the cover bars being provided with openings 18 through which the binding strips are arranged, the clamping bars having openings 19 for the binding strips alined with the openings 18 of the cover bars. The openings 18 of the cover bars are deep cnough so that the binding strips swing freely therein no matter what position the clampln bars assume relative to the covers. Strips are secured to the cover 3 by means of the tongues 20 formed integrally with its cover bar, the tongues being turned inwardly to engage holes 21 in the binding strips. The binding strips are adjustably secured to the other cover by means of the ratchet bar 22, on which ythe binding strip' member 23 is slidably mounted. The pawl 24 is pivoted at 25 on the under side of the member 23 to coact with the ratchet bar. The outer end'of the pawl is extended laterally and turned up to provide a finger piece 26 which engaging the edge of the adjusting member 23, serves as a stop for the pawl in one direction. The pin 27 limits thc movement of the pawl -in the other direct-ion. A U-shaped spring 28 is mounted on the stud 29 to engage the pawl and serves to hold the pawl yieldingly in its engaging or disengaging position. The adjusting member 23 has finger holds 30 on its forward edge so that the member may be conveniently grasped for retracting the binding strips. These features of the attachment for the binding strips `to they cover, the clamping bars and adjusting means so far described, are substantially the same as those of my said patent referred to.

To apply clamping stress to the binding strips, I provide an adjusting lever 31 arranged to coactI with the ratchet bar 22, the bar being preferably a double ratchet or toothed on each edge. This' lever is mounted on the pivot 32 on the adjusting member to coact with the bar as stated, for drawing up the binding strips or applying tension thereto. The lever 31 is preferably provided ,with a plurality of rack engaging teeth 33. When the lever is in its initial' position, as shown by full lines in Fig. VII

and by dotted lines in Fig. VI, it is out of engagement with the rack. When the lever is actuated however, the teeth are brought into engagement with the rack. To permit repeated actuation of the lever in tightening the binding strips, I arrange the pivot 32 in a slot 34 in the adjusting member, the slot being inclined so that the lever can be disengaged from the ratchet bar while the lever is still in its actuated position, and this permits repeated engagement and actuation of "tl le lever.

The lever is automatically disengaged in releasin the binding strips. In releasing the binding strips, it 1s only necessary to disengage the pawl 24 which automatically disengages the lever, should it remain in engagement with the rack bar after the adjustment is completed. A stop pin 44 -is provided for the lever to limit its actuat- 'Ihe bindingv 'in the art to which4 this invention relates. I

ing movement. By this simple means, the. binding strips may be quickly drawn up to clamp the sheets or leaves. Ordinarily, it

is not necessary to manipulate the lever as the binding strips can be drawn sufficiently taut by hand. If, however, it is desired to further tighten them, it can be quickly done through the adjusting lever 31'.

The back strip 35 telescopes into the cover chambers which are open on the outside of the cover bars to receive the same. back strip 35 is yieldingly connected to the cover 1 by means of the rod springs 36 arranged in an extension 37 of the chamber 7. The springs 36 are secured as by the rivets 43 on opposed sides of the recess extension 37 with their free ends overlapped or crossed. The free v,ends of the springs are connected by the cord 38 to the back strip 35, the cord being looped over'the button 39 on the back strip, its ends being secured to the ends of the springs. This spring connection can be embodied in a short thin cover and the connection serves to assist in keeping the back strip properly centered. The other end of the back strip is connected to the adjusting member 23.

To cover the end of the back strip, and to prevent its being displaced or disarranged during the manipulation of the adjusting mechanism, I provide the chamber of the cover 2 with a partition plate 40. This partition plate is referably formed integrally with the cover ar 11. The back strip projects into the cover at the rear of this plate, the chamber in front of the plate being open'- to permit the manipulation of the adjusting mechanism. The plate 40 is longitudinally slottedat 4 1 to receive the studs 42 on the adjusting member, the studs also serving to connect the binding strips to the adjusting ymember. The plate 40 is provided with integral attaching lugs 45 for .the bar` 22. The bar thus mounted on the cover is carried so that the strain on the binding cords is effectively distributed in the cover, and although made of light material, is not likely to be distorted thereby. i

With the parts thus arranged, the back is automatically adjusted and at the same time is concealed in the cover, although the adjusting mechanism is arranged in the lopen ,recess of the cover for convenience in'manipulation. I

My improved binder is very simple and economical in structure, is quickly adjusted, and'is compact and light in weight.
